You looking for the external accessory hose or the internal supply hose. I have the internal one I just purchased from another member...thought I was getting the accessory hose. Still looking for one myself. You can usually find a new kit on eBay for around $60.
I have 3 extras. $40 each shipped USPS flat rate priority box, next business day from payment in the continential US. Paypal ok. PM me for my payment info. I have a busy weekend, may not respond immediately.
